Ken Paxton, the Republican attorney general of Texas and a former state legislator, has been indicted by a grand jury on charges of securities fraud and of failing to register with the state securities board, officials said. The grand jury in the northern Dallas suburb of McKinney handed up a three-count indictment against Mr. Paxton on Tuesday, the officials said. The indictment is to be unsealed on Monday, when Mr. Paxton is expected to turn himself in to the authorities at the Collin County Jail. The charges — two counts of first-degree securities fraud and one count of third-degree failure to register — are tied to Mr. Paxton’s work soliciting clients and investors for two companies while he was a member of the Texas House of Representatives, before he was elected attorney general in November.
